Application med A ril 5,

To all whom it may concern:

Be it known that'l, CHARLES Davmorr,

a citizen of the United States, residing at the case for inspection and repair.

Another object of my invention is to provide a new and improved form of wrist watch consisting of a case portion, a cover portion and a movement carrying or hearing portion which will be so connected that the device can be uickl and economically manufactured an can e easily inspected or repaired.

Another object of my invention is to provide a watch, and more particularly a wrist I .watch, of the type above specified which can be used in combination with a chain or a ribbon for holding iton the wrist of the wearer.

Another object of my invention is .to provide a new and improved watch, and more particularly a wrist watch, in which the cover portion .and the movement-bearing portion are urged away from the case portion by means of springs and are-normally held in place by a suitable latch.

Other objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof.

Fig. 1 is a side elevation.

Fig. 2 is a top view.

Fig. 3 is a detail view partially in section.

Fig. 4 is a detail sectional view.

The watch has a case portion 2 having the. shape shownin Fig. 3 and provided with lugs or brackets 4 havin the shape shown in Fig. 2 and in Fig. 3. aid lugs or brackets '4 can be connected to the case portion 2 by any suitable method,

such as soldering and the like.

The bracket portions 4 are preferably provided with hook-like and inwardly bent pro 1928. Serial No. $30,030.

jections 4 for a purpose to be later described.

The cover portion 1 of the watch is provided with a suitable transparent glass or crystal top T, and it is provided with perforated ears 5 which are secured thereto by any suitable method, such as soldering. The movement carrying member 3 is also provided with similar erforated ears 5. The

parts are so dimensioned thatthe ears 5 of the cover portion 1,for example, snugly fit against the brackets 4 provided at one end of the casing 2 so that the members 4 and 5 can be connected by means of a pintle 8 which is rigidly secured to the lugs 4 by hammering the ends of the said pintle 8 so as to enlarge them'so as to give the cfi'ect of a rivet.

.The pintle 8' is provided with a torsion spring 7 and one end thereof is bent over so as to firmly hold on to one of the brackets 4 before the said spring 7 is put under'torsion. After'this is done and before thesleeve 6 is applied, the other end of thesaid spring 7 is secured to the opposite ear 5 and bent into position, as shown in Fig. 4 so that it remains in said position and the spring 7 is preferably placed under slight torsion when this'is done so that the saidspring 7 tends to force the cover 1 into the position shown in Fig. 3 and against the ends 4 which prevent the-said cover part 1 from being moved backwards away afr'om the vertical position. A similar spring 7 mounted in a similar manner operates on the movement-carrying portion 3.

The movement-carrying portion fits directly into the case 2 but projects above the said case and it is provided with the ordinary crown C for winding the watch. The cover portion 1 is provided with a notch or races so that it can fit snugly over the movement carrying portion and it is also provided at the outer end thereof with'a spring latch 9 which snaps over the case 2 so as to firmly hold the parts in position. Of course by releasing the catch or latch 9 the parts are automatically moved. into the position The springs 7 are covered by means of sleeves 6 which are applied after the before mentioned parts have been assembled. In

- the embodiment shown herein the sleeves 6 I 5 the movementcarrying are connected to a chain F but of course my invention isnot limited to a watch which is used in connection with achain asthe watch could be secured in. position by means of a; ribbon if desired, the said ribbon being suitably passed around the sleeves 6. v

I have described a preferred embodiment of my invention but it is clear that numerous having two pairs.v of perforated externallugs secured thereto, a-movement-carrying portionhaving'a pair oi perforated lugs adapted to be placed within one ofthe before mentioned pairs of lugs, a pintle passing through the adjacent lugs of the said case portlon and of the said movement- .carrying. portion andadapted to movably coverportion.

me ses connect them, a torsion springlocated on the said pintle and connected to the said case portionand to the said movement-carrying portion and adapted to urge the. said movement-carrying portion away from thesaid case portion, said movement-carrying portion being adapted to fit into the said (Tase ortion a cover 'ortion havin a air of perforated lugs adapted to beplaced within the other of the before mentioned pairs of lugs, a pintle passing through the adjacent lugs of the case portion and of the said cover portion and adapted. to movab'ly connect them, a torsion spring located on said pintle and connected to the said case portion and to the said cover portion adapted to urge the cover portion away from the case portion.

2. A device according to vclaim 1 in which the perforated external lugs' secured to the case portion have inwardly bent ends which are" adapted to limit the movement of the movement carrying portion and of the H testimony whereof signature. r i
